Publica and LiveRamp expand partnership to scale people-based CTV targeting

This partnership addresses the critical challenge of identity fragmentation in the connected TV ecosystem. By embedding people-based identifiers into the ad server and auction tools, Publica provides publishers with the infrastructure to compete for high-value budgets migrating from linear TV. For the broader industry, it reinforces the move toward deterministic identity as a replacement for cookies and IP-based tracking. Success here will depend on publisher adoption rates; watch for whether Publica's current Tier 1 partners, such as Samsung Ads, report significant yield lifts from these enhanced audience segments in the coming quarters.

The expansion of this partnership arrives as the CTV industry moves toward a 'multi-ID' reality, according to MarTech (March 2026). With nearly 36% of desktop and 54% of mobile impressions now lacking traditional identifiers, publishers are increasingly layering multiple identity frameworks like LiveRamp's RampID, Unified ID 2.0 (UID2), and ID5 to maintain addressability. This shift is critical as advertisers prepare for major spending cycles; per LiveRamp (April 2026), nearly 90% of U.S. households now own a CTV device, making verified, person-based outcomes a requirement for brands moving large budgets into the space.

Publica's role in this ecosystem has been fortified by its acquisition by Integral Ad Science (IAS) for $220 million in August 2021. According to IAS, publishers using the Publica platform have seen an average 30% lift in yield. This puts Publica in direct competition with Magnite, which solidified its own CTV ad server dominance through the 2021 acquisitions of SpotX and SpringServe. Per Jounce Media (March 2025), Magnite continues to cover roughly 99% of the CTV supply market, but infrastructure-level integrations with major identity providers like LiveRamp allow smaller, specialized players like Publica to chip away at that lead by offering deeper targeting data.

Furthermore, the competitive landscape for identity is shifting due to agency-level consolidation. Per The Current (June 2026), Publicis recently acquired LiveRamp, sparking debate regarding the future of the platform's neutrality. This move has reportedly prompted rival holding companies like Omnicom to accelerate the development of their own proprietary ID solutions to avoid dependence on a competitor's data layer. Despite these shifts, LiveRamp remains a primary framework for premium CTV destinations like Netflix, Disney, and Paramount, according to company reports from early 2026.
